https://getbooksolutions.com/download/solution-manual-foraccounting-information-systems-11th-edition-by-bodnar Chapter SYSTEMS TECHNIQUES AND DOCUMENTATION TEACHING TIPS I normally introduce flowcharting symbols with simple examples on the board I first introduce a very simple manual flowchart involving only three symbols An example would be the preparation of a sales order This would show a customer order coming into the process and a completed sales order coming out Then I mention how computer symbols could be added From experience, I have discovered that the single most important thing for students to learn in analytical flowcharting is the sandwich rule About 90% of all mistakes seem to involve a violation of this rule The second largest problem involves separating various functions (e.g., sales, credit, shipping, and so on) into columns I've discovered students all seem to about the same when I place complicated flowcharting problems on exams For this reason, I now ask mostly short answer questions about flowcharting on exams I've found it important to emphasize the distinction between the types of documentation tools used by systems developers and auditors With logical data flow diagrams (DFD), it's interesting to discuss how developers go from an existing system to a new system They begin with an existing analytical flow chart, turn it into a DFD, modify the DFD, and then generate a new analytical flowchart It’s worth taking some time to discuss the BPMN, as this is used in Chapters 7-9 to document the basic transaction cycles 11 12 Systems Techniques and Documentation USERS OF SYSTEMS TECHNIQUES Systems techniques are tools used in the analysis, design, and documentation of system and subsystem relationships They are used by accountants who systems work, either internally for their company or externally as consultants or auditors Most auditing engagements are divided into two basic components: the interim audit, which involves internal control evaluation, and the financial statement audit, which involves substantive testing Substantive testing is the direct verification of financial statement figures, placing such reliance on internal control as the results of the interim audit warrant Internal Control Evaluation Analytic flowcharts, document flowcharts, and forms distribution charts may be used by auditors to analyze the distribution of documents in a system Several other system techniques, such as questionnaires and matrix methods, might also be used in the evaluation of internal controls Compliance Testing Auditors undertake compliance testing to confirm the existence, assess the effectiveness, and check the continuity of operation of internal controls on which reliance is to be placed Working Papers Working papers are the records kept by an auditor of the procedures and tests applied, the information obtained, and conclusions drawn during an audit engagement Auditors use systems techniques to document and analyze the content of working papers Internal control questionnaires, analytic flowcharts, and system flowcharts appear frequently in working papers because they are commonly used by auditors in the evaluation of internal controls Data flow diagrams, HIPO charts, program flowcharts, branching and decision tables, and matrix methods might appear in working papers if they are part of the documentation of a system that is being reviewed Use of Systems Techniques in Systems Development A systems development project generally consists of three phases: systems analysis, systems design, and systems implementation Systems Analysis Logical data flow diagrams and analytic flowcharts are helpful in giving an overall picture with regard to transaction processing within the organization Systems Design Systems design formulates a blueprint for a completed system Systems Implementation Systems implementation involves the actual carrying out of the design plan Systems Techniques and Documentation 13 Use of Systems Techniques by Sarbanes-Oxley Act Compliance Participants System documentation is the underpinning support of the internal control and process documentation requirements that have been set by the Sarbanes-Oxley Act (SOX) SYSTEMS TECHNIQUES Flowcharts are probably the most common systems technique A flowchart is a symbolic diagram that shows the data flow and sequence of operations in a system Flowcharting Symbols The basic symbols include the input/output symbol, the process symbol, the flowline symbol, and the annotation, comment symbol The flowline symbol is used to link other symbols Specialized input/output symbols may represent the I/O function and, in addition, denote the medium on which the information is recorded, or the manner of handling the information, or both If no special symbol exists, the basic I/O symbol is used Specialized process symbols represent the processing function and, in addition, identify the specific type of operation to be performed on the information If no specialized symbol exists, the basic process symbol is used The additional symbols are used to clarify a flowchart or to make the flowcharting of a complete process more convenient Symbol Use in Flowcharting Normal direction of flow is from left to right and top to bottom IPO and HIPO Charts IPO and HIPO charts are used primarily by systems development personnel A HIPO chart contains two segments: the hierarchy chart that factors the processing task into various modules or subtasks and an IPO chart to describe the inputprocess-output requirements of each module The hierarchy chart describes the overall system and provides a "table of contents" to the detailed IPO charts, usually through a numbering scheme Systems and Program Flowcharts Systems flowcharts are associated with the analysis phase of a systems project and program flowcharts with the design phase A program flowchart is the design step between overall system design and coding the system for computer processing A systems flowchart identifies the overall or broad flow of operations in a system 14 Systems Techniques and Documentation A program flowchart (also called a block flowchart) is more detailed concerning individual processing functions than a systems flowchart Each of the processing functions depicted in a systems flowchart is further detailed in a program flowchart, similar to the successive layering of IPO charts in HIPO Logical Data Flow Diagrams Logical data flow diagrams or data flow diagrams (both abbreviated as DFD) are used by systems analysts to document the logical design of a system to satisfy the user's request There are four DFD symbols The terminator is used to indicate a source or a destination of data The process indicates a process that transforms data The data store is used to indicate a store of data The data flow is used to indicate a flow of data Although these terms and symbols are representative, many variations exist Structured Analysis DFD typically shown in layers of increasing detail, with the DFD in each layer being linked to each other Analytic, Document, and Forms Distribution Flowcharts Analytic flowcharts, document flowcharts, and forms distribution charts may be used to analyze the distribution of documents in a system An analytic flowchart identifies all significant processing in an application, emphasizing processing tasks that apply controls A document flowchart is similar in format to an analytic flowchart but contains less detail about the processing functions A forms distribution chart illustrates the distribution of multiple-copy forms within an organization Analytic Flowcharting Illustration Planning the Flowchart Flow is from top to bottom and left to right Symbol Selection For manual system, only several symbols are needed; symbols for documents, files, and processes are the most commonly used symbols System Analysis One must first understand the system to be flowcharted Drawing the Flowchart Sandwich Rule Every process symbol should have its inputs and outputs clearly specified Use of Connector Symbol This symbol is used to terminate the flowchart and then continue it on another page or in a different column Entity-Column Relations Columns in the flowchart typically represent individuals or departments This is something that beginners often have Systems Techniques and Documentation 15 difficulty with Unified Modeling Language (UML) UML is a technology that assists in the specification, visualization, and documentation of models developed to structure and design software systems UML uses a variety of graphical techniques to model different aspects and views of software development projects at various levels of abstraction In addition to techniques used to model the specifics of software development, UML includes techniques that are the functional equivalent of data flow diagrams, document flowcharting, and analytical flowcharting UML version 2.0 defines thirteen types of diagrams, divided into three categories: structure diagrams, behavior diagrams, and interaction diagrams When used to model business processes, the graphical techniques used in UML to prepare activity diagrams can result in diagrams that are very similar to analytic flowcharts Business Process Diagrams The Business Process Diagram (BPD) is a graphical representation of a business process It focuses on the sequence of activities that constitute a business process, and also on the related business logic that guides that sequence of activities Business Process Modeling and Notation (BPMN) is a widely accepted standard for modeling business processes using BPDs Similar to UML, BPMN is a computer industry specification standard developed and supported by the OMG, a nonprofit computer industry consortium BPMN is similar to UML but differs in that BPMN is a process-oriented approach to modeling whereas UML is an objectoriented approach Where BPMN has a focus on business processes, UML has a focus on software design Narrative Techniques Interviews are useful for familiarizing the analyst with decision makers and their problems Depth interviews allow the systems analyst to establish a personal working relationship with the manager Open-ended questionnaires are a factgathering technique where persons provide written answers to general, rather than specific, questions Narrative techniques also include document reviews Resource Utilization Analysis Flowcharts not show the resources required to operate the system Such resources must be considered both by the auditor and systems persons Work Measurement Work measurement includes the variety of techniques used to model, measure, or estimate clerical or other activities in a production framework In an accounting 16 Systems Techniques and Documentation framework, work measurement is similar to the concept employed in standard cost systems Work Distribution Analysis Work distribution analysis studies the assignment of specific tasks to employees A task list is typically used to record each separate item of work performed by an individual and the average number of hours spent on each task per week Decision Analysis Techniques Branching and Decision Tables are used primarily by systems development personnel Often the decision logic required in a computer program is sufficiently complex to mitigate the usefulness of the standard decision flowcharting symbol In such cases, a branching table may be used to depict a decision function A decision table is a tabular representation of a decision-making process It is similar to a branching table but more complex in that it incorporates multiple decision criteria Decision tables are constructed on an IF-THEN premise and appear as a two-dimensional matrix in general form Matrix Methods Matrix methods are used by both auditors and systems personnel to present large volumes of data The "work" or "spread" sheets used in accounting systems to spread or distribute account balances through different subclassifications or to facilitate the closing process are common examples of matrix techniques Software for Systems Techniques A variety of software tools can be used to create flowcharts and other graphical systems techniques Microsoft Office® Applications Microsoft Visio® is a Microsoft Office® application that is targeted at the creation of flowcharts and other graphical diagrams Microsoft PowerPoint® is a general presentation tool that contains specific drawing features that may be used to create flowcharts and other graphical diagrams These same drawing tools are also available in both Microsoft Word® and Microsoft Excel®, allowing either of these general software applications to be used to prepare graphical diagrams and flowcharts Computer-Aided Software Engineering (CASE) Computer-aided software engineering (CASE) is the process of using computer software technology that supports an automated engineering discipline for software development and maintenance UML Modeling Tools A variety of software tools to draw UML charts are available from vendors Professional UML software is similar to CASE in Systems Techniques and Documentation 17 its objectives and its potential benefits in that it integrates UML charts with other aspects of systems development, such as database design and code generation REVIEW QUESTIONS A flowchart is a symbolic diagram that shows the data flow and sequence of operations in a system The basic symbols include the input/output symbol, the process symbol, the flowline symbol, and the annotation, comment symbol See Figure 2.1 for the symbols Flowchart symbols represent the physical aspect of a system An IPO chart provides very little detail concerning a processing function, but is a useful technique for analyzing overall information requirements Additional processing detail is provided by HIPO charts A HIPO consists of a series of charts that represent systems at increasing levels of detail, where the level of detail depends on the needs of users An analytic flowchart is similar to a systems flowchart in level of detail and technique, but is organized by columns A logical data flow diagram can be used to document the logical aspect of a system Auditors use analytic flowcharts in the evaluation of internal controls Organization of the chart by columns is common to analytic, document, and forms distribution charts There are four symbols The terminator is used to indicate a source or a destination of data The process indicates a process that transforms data The data store is used to indicate a store of data The data flow is used to indicate a flow of data See Table 2.1 for the symbols 10 No, flowcharting is not useful in analyzing the resources required to implement a system 11 Work measurement is useful in evaluating the technical feasibility or 18 Systems Techniques and Documentation technical requirements of a system design 12 A work distribution analysis requires detailed information about functions and responsibilities A task list is used to record each separate item of work performed by an individual and the average number of hours spent on each task per week Each employee (or department, and so on) is represented by a column; the work assignments are spread across the table to employees The method of assignment should be rational; that is, employee qualifications, internal control, scheduling, timing of events, and so forth should be considered Systems Techniques and Documentation 19 ANSWERS TO DISCUSSION QUESTIONS AND PROBLEMS 13 - 18 Multiple-Choice (CPA) 13 B 14 C 15 D 16 D 17 C 18 C Varies 19 Systems Design - 30 minutes Hard This problem provides an opportunity for the student to appreciate the data processing requirements of transactional data Many students will not appreciate the amount of effort necessary to manually develop the 21 desired subtotals There are a variety of solutions, including going through the initial batch 21 times for 21 subtotals The data processing steps required (and overall efficiency) depend on the approach taken Experience has shown that many student-generated solutions are not effective: examined in detail they fail to generate the 21 subtotals A suggested solution is as follows: (1) Sort the batch of invoices into piles: invoices showing only product sales and those invoices with product and/or sales (2) Sort the pile of invoices containing only product sales by customer Calculate daily sales totals for each customer Calculate the grand total Post (transcribe) these subtotals to the worksheet (3) Sort the pile of invoices with product lines and/or sales by customer Either go through each customer pile twice, calculating each required subtotal; go through each pile once, accumulating two subtotals concurrently (this is not possible using a single calculator or with a single adding machine as two totals are being accumulated); or re-sort each pile into piles: product only, product only, and mixed Calculate subtotals for each customer and transcribe to the worksheets (Note: the mixed invoices have to be examined when calculating both line and line subtotals.) 20 Systems Techniques and Documentation 20 Analytic Flowchart; Data Flow Diagram - 45 minutes Medium a analytic flowchart Systems Techniques and Documentation 23 the information is presented in a concise, graphic manner which is easy to comprehend and visualize It creates more interest on the part of the audit staff because they can better appreciate the functioning of the system and hence the reasons for tests It produces more valuable and realistic recommendations to clients on internal controls and system efficiency because of increased awareness of accounting systems, relationships, and document flows It emphasizes those areas of the internal control system (and related accounts) which require more or less attention and therefore assists in better use of audit time It increases client goodwill because new audit staff members usually require less time for system orientation, and interference with the client's staff is kept to a minimum 24 Systems Techniques and Documentation 24 Analytic Flowchart - 30 minutes Medium Systems Techniques and Documentation

instructor might wish to expand on some complexities related to the above type of calculations in actual practice, such as ensuring valid and accurate sample sizes, ensuring realistic test conditions, ensuring accurate count of rest and delay times, and the usefulness of such averages in general Systems Techniques and Documentation 33 Analytic Flowchart - Hour Medium 31 32 Systems Techniques and

Prepare Flowcharts Using Microsoft Office Flowchart Symbols - Varies Systems Techniques and Documentation 35 The solutions to the problem are the flowcharts in the textbook that the student is expected to reproduce using Microsoft Office flowchart symbols These are Figure 2.17, Figure 2.18, and Figure 4.7 Figure 2.17 has symbols and would not take very long to reproduce The other two figures would take much more time as Figure 2.18 has 29 symbols in three columns and Figure 4.7 has 18 symbols in three columns 38 A D G event sequence pool B E H activity message flow lane I C gateway F association data object 39 Errors in the use of symbols in the BPD figure ‘authorize order’ symbol should be activity symbol (oval) not an event symbol (circle) message flow symbol (dashed line) should replace sequence flow symbol (solid line) between ‘authorize order’ and ‘prepare order’ ‘customer database’ should be data object symbol, not event (diamond) symbol association symbol (dotted line) should replace solid line between ‘prepare order’ and ‘customer database’ sequence flow line between ‘prepare order’ and ‘ship order’ should have arrowhead going into ‘ship order’ association symbol (dotted line) should replace solid line between ‘ship order’ and ‘shipping notice’ message flow symbol (dashed line) should replace sequence flow symbol (solid line) between ‘ship order’ and ‘customer’ pool 40 Figure 8.8 in the textbook is the solution (i.e., correctly-prepared version of problem figure) The three data objects should be connected with dotted association lines to an activity symbol (oval) that encloses ‘process completed transaction.’ Message flow symbols (dashed lines) should connect to the ‘accounts receivable’ and ‘general ledger’ pools 41 Business process diagram for Salt Company 36 Systems Techniques and Documentation WEB RESEARCH ASSIGNMENTS 42 Both SmartDraw and Visual-Paradigm support BPMN Visual Paradigm, however, is part of a fairly strong suite of visual development tools, whereas SmartDraw is a generic drawing program 43 The UML standard incorporates 13 different types of diagrams One of those types, the Activity Diagram, is very similar to the BPMN diagram BPMN has the specific advantage of being able to convert directly into program code using a Business Process Execution Language (BPEL) Otherwise, UML provides a much more comprehensive way to document information systems 44 In recent CPA exams, the candidate has been called on to interpret analytic flow charts in dealing with case-type questions Systems Techniques
